✦ Synopsis
Th? ingestion of mineral particles by Biomphalaria glabrutu is proved and the importance of thcsr particles in the diet of the snails is investigated. The number of particles ingested rises with the size of the snails and they arc retained in quantity in the alimentary tract whcn an adequate supply is not provided. The size of grit found in the gut differs widely from the mixture offered.
Mineral particles are ingested actively and selectively.
Quantitative investigations comparing snails ciiltured with and without sand showed a slight advantage concerning growth and reproduction for snails cultured with sand.
